title: Detection of deoxyribonuclease activities of Mycoplasma pneumoniae.
abstract: Alkaline deoxyribonuclease activity was detected in culture of Mycoplasma pneumoniae. This enzyme required MgCl2 to stimulate its activity and preferred double-stranded to single-stranded DNA as substrate. By using polyacrylamide gel electrophoresis or isoelectric electrofocusing, two distinctive deoxyribonuclease activities were demonstrated both in cultured broth and cell homogenate.
